*) Rather than duplicate in various buggy ways the application of CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files), centralize it in Makefile.rules. UNPROFILE_OBJS mustn't be listed in USER_OBJS but are compiled as such. I've also verified that unprofile didn't work in the current form, because we set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong), which is normally used by c_flags, but we also override c_flags for all USER_OBJS, and there we don't call unprofile. Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ. We need to set c_flags (which is not a public Kbuild API) to clear a lot of compilation flags like -nostdinc which Kbuild forces on everything. *) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses CFLAGS_anObj.o, like done by Kbuild. *) Make c_flags apply to all targets having the same basename, rather than listing .s, .i, .lst and .o, with the use (which I tested) of $(USER_OBJS:.o=.%): c_flags = ... and of - $(obj)/unmap.c: _c_flags = ... + $(obj)/unmap.%: _c_flags = ...
